Athletics event broadcast live in first month (7)
I believe the answer is:
javelin
'athletics event' is the definition.
'javelin' can be an answer for 'event' (javelin is a kind of event). I'm not sure about the 'athletics' bit.
'broadcast live in first month' is the wordplay.
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'in' indicates putting letters inside.
'first month' becomes 'jan' (abbreviation for January).
'live' anagrammed gives 'veli'.
'veli' going within 'jan' is 'JAVELIN'.
Can you help me to learn more?
(Other definitions for javelin that I've seen before include "Athletics missile" , "Field event projectile" , "It's thrown in a field event" , "Sporting spear" , "Spear for throwing" .)
